The former couple had got into an argument after Nicole was said to have snubbed Simpson when he interrupted a meal she was having at a restaurant with their children.
O.J. said he went home and kept getting angrier and angrier and worked himself into an absolute rage. Simpson told the producer he "didn't like the way she treated me in front of the kids at the restaurant. I didn't like that she was routinely having guys have sex with her at her condo with the kids there".
"I went over there to give her a piece of my mind," he was quoted as saying.
When he arrived and no one answered at the house, he started pounding the door and shouting, according to the report.
The door then swung open and Nicole was standing there with a kitchen knife in her hand.
O.J. told the producer "she was yelling go away! Go away! And waving the knife around at me. At one point she was lunging at me with the knife and I was just trying to talk to her". Nicole stepped out of the apartment - slashing the knife in the air.
'"I was in such a rage that something just snapped. I couldn't take her constant taunting of me with other men or her using drugs and drinking while my kids were living with her. I went beserk. Before I knew what I was doing I took the knife away from Nicole and started slashing at her. I cut her over and over again until she was lifeless. I was shocked at my own anger - I had killed the woman I had loved for so long."
